Class 292
CLOSURE FASTENERS
Class Definition:
This class includes all bolt elements and latching devices,
not combined with lock structure, for securing in closed or
adjusted position any closure element, such as a door,
window, gate, trunk-lid, box-cover, bag-frame, or the like.
REFERENCES TO OTHER CLASSES
SEE OR SEARCH CLASS:
49, Movable or Removable Closures, appropriate subclasses,
particularly subclasses 276+ for closure-fasteners when
combined in or with closure-operators, and this class (292)
for devices for starting a closure open, or drawing it from a
substantially closed to a fully closed position, wherein such
operation is accomplished by cooperating surfaces on the
latch bolts and keepers which function during movement of the
bolts into or out of latching position relative to the
keepers.
70, Locks, for key or combination locking devices.
99, Foods and Beverages: Apparatus, subclasses 349+ for
fasteners combined with food compacting followers and
subclass 402 for fasteners associated with hinged bread
toaster grids.
109, Safes, Bank Protection, or a Related Device, subclasses
62+ for devices for safes and vaults commonly known as
pressure mechanisms, the function of which is to cam the door
tight in its jamb, and which usually serve to crack the door
to an ajar position, and subclass 63.5 for devices for
receptacles which render the closure fastener thereof
ineffective when the receptacle is in a condition of abnormal
use.
220, Receptacles, subclasses 315+ for receptacle closure
fasteners.
221, Article Dispensing, appropriate subclasses for article
dispensing devices not otherwise provided for, having means
to retain mechanical article releasing closures or article
ejecting discharge assistants in article dispensing or
nonarticle dispensing position, and see particularly
subclasses 151+ and 154 for article dispensers having means
for blocking or disabling ejector or releaser means and lock,
latch or seal structures for supply containers and/or their

devices having means to latch or secure closures, valves and
the movable parts of discharge assistants in a desired
position, especially subclass 44 for a combined indicator
